220-1201 Practice Question: That their laptop's 1TB hard drive is making a…
A user reports that their laptop's 1TB hard drive is making a clicking sound and the system is running very slowly. The technician runs a diagnostic and finds multiple bad sectors. What should the technician do first?
⚠ Common exam trap
220-1201 often tests the 'data first' principle — candidates are tempted to jump to repair or replacement steps, but the exam expects backup of data before any remediation on a failing drive.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Back up all important data to an external drive or cloud storage.
Clicking noises plus multiple bad sectors strongly indicate imminent mechanical failure of the hard drive. The technician's first priority is to preserve the data by backing it up to external or cloud storage before any further diagnostics or remediation, because continued operation risks total loss.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Run a surface scan to mark bad sectors and continue using the drive.
Why it's wrong here
A surface scan to mark bad sectors only prevents the operating system from writing to those specific areas. However, the clicking sound is a critical indicator of a severe mechanical failure, likely involving the read/write heads or platters. Marking bad sectors does not address the underlying physical degradation, which will inevitably lead to further drive failure and data loss, making continued use highly risky.
- ✗
Replace the hard drive immediately and reinstall the operating system.
Why it's wrong here
While replacing a failing hard drive is ultimately necessary, doing so immediately without attempting data backup is premature and risks permanent data loss. The primary concern with a failing drive exhibiting clicking sounds is to preserve the user's valuable data. Reinstalling the OS on a new drive before securing existing data means any unbacked-up files on the old drive could become unrecoverable if it completely fails during the replacement process.
- ✓
Back up all important data to an external drive or cloud storage.
Why this is correct
The clicking sound, combined with reports of bad sectors, strongly indicates an imminent mechanical failure of the hard drive. Before any other action, the absolute priority is to mitigate potential data loss by backing up all critical user data to a reliable external drive or cloud storage service. This proactive measure ensures data preservation, as the drive could cease functioning completely at any moment, making subsequent data recovery significantly more difficult or impossible.
- ✗
Update the hard drive firmware to fix the clicking noise.
Why it's wrong here
Updating hard drive firmware is designed to address software bugs, improve performance, or enhance compatibility, not to resolve physical mechanical failures. A clicking sound is a definitive symptom of a hardware problem, typically involving the read/write heads or spindle motor, which cannot be corrected by a software-based firmware update. Attempting this action would be ineffective and waste critical time while the drive continues to degrade.
